UNHTED STATES WILLIAM F. CLAYTON, OF'HUN'TSVILLE, ALABAMA.

IPICKER-STICK GI-IEGK FOR LOOMSQ To all whom it may concern:

Be it known that I, I/VILLIAM F. CLAYTON, a citizen of the UnitedStates, residing at Huntsville, in the county of Madison and State ofAlabama, have invented certain new and useful Improvements in Picker-Stick Checks for Looms; and I do hereby declare the following to be afull, clear, and exact description ofthe invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in picker-stickchecks for looms, and more particularly to that class of looms in whichthe shuttle checking is accomplished by the action of the check on thepicker-stick. The main object of this invention is the provision of acheck of the above character which can be quickly and readily adjustedso as to be disposed in its proper relative position whereby to receivethe blow of the picker-stick.

Another object of the present invention is the provision of a deviceadapted to be used for retaining the picker-stick in true alignment withthe lay so as to enable the pick motion of the loom to throw the shuttlein a direct line from one shuttle box to the other, and at the same timeretain the shuttle in its correct position in the shuttle box of thehopper end.

lVith the above and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of partshereinafter more fully set forth, pointed out in the claims and shown inthe accompanying drawings, in which:

Figure 1 is a side elevation of a checking device constructed inaccordance with my invention illustrating the application of the same tothe lay of a loom, and

Fig. 2 is a horizontal sectional View taken on the line 2-2 of Fig. 1.

In the accompanying drawings my improved checking device is attached tothe lay of the loom which is generally indicated by the numeral 1. Themain supporting element includes a U-shaped frame 2 having one of itsarms projecting somewhat beyond the other arm as at 3 and disposed atone side of the picker-stick 4. The frame 2 is suspended beneath the lay1 by means of the bracket 5 connected to the extended arm 3 and havingan arm 6 connected at one end to the bracket 5 by means of the bolt 7the other end of the arm 6 being riveted or otherwise secured to the layl.

Specification of Letters Patent. Patented June 27, 1922'.

Application filed January 25, 1922,

Serial No. 531,696.

The picker=stick 4 is retained in its proper relative position so as toreceive the blow of the shuttle and throw the shuttle in a direct linefrom one shuttle box to the other, by means of the spring arms 8, theinner ends of which are connected by means of the bolts 9 to the sideportions of the frame 2 preferably upon the inner sides of the frame andextend outwardly beneath the lay 1, the outer ends of these spring armsbeing curved inwardly toward each other whereby to pro= vide africtional grip for the opposed faces of the picker-stick. These opposedfaces of the spring arms 8 are provided with pads 10, which may be ofleather or any other suitable material of a like character whereby whenthe picker-stick is moved therebetween they will tend to assist inretarding the movement of the picker-stick.

My improved check includes an arm 11 suspended from the extended end 3of the frame and mounted for adjustment upon the bolt 12. This arm 11may be adjusted upon the bolt 12 and retained in various adjustedpositions by means of the nut 13 threaded upon said bolt. Connected tothe lower end of this arm 11 by means of the bolt 14 is an angular plate15 and mounted upon the end of this plate which extends at right anglesto the arm 11 is a supporting staff 16, the lower end of which ismounted for adjustment upon the end of the plate 15 by means of the boltand nut 17 Upon the upper end of this staif 16 is a buffer including anarcuate shaped plate 18 having a suitable pad 19 attached to its innerface which may be formed of felt or any other suitable material wherebyto receive the impact of the picker-stick 4 upon its outward movement oras it moves to a position to receive and throw the shuttle to theopposite shuttle box.

In order to adjust the tension of the spring arms 8, set screws 20 arecarried by the side portions of the frame 2 and adapted to extendtherethrough for engagement with the arms 8 as illustrated in Fig. 2,whereby the arms 8 may be readily adjusted to retain the picker-stick 4in its proper relative position.

In order to receive the blow of the pickerstick 4 at the right time, thebufi'er may be readily adjusted to the proper relative position throughthe adjustment of the staff 16, plate 15 and arm 11. The staff 16 ismounted for adjustment upon the bolt 17 whereby the buffer may beadjusted angularly and the plate 15 is mounted for adjustment upon thebolt 14 sothat the staff may be adjusted ver- 1 buffer member mountedfor vertical and angular adjustment upon said frame and disposed in thepath of the picker-stick.

2. A device of the class described including a frame, means forsupporting said frame beneath the lay of a loom, a pivotally mounted armsuspended from said frame and a buifer member mounted for vertical andangular adjustment upon the lower end of said arm and disposed in thepath of the picker-stick.

8. Adevice of the class described includ-' ing a frame, means forsupporting said frame beneath the lay of a loom yieldable guide armsarranged in opposed relation and supported by said frame between whichthe picker-stick of the loom moves and a buffer member mounted forvertical and frame beneath the lay of a loom, opposed spring guide armscarried by said frame between which the picker-stick of the loom moves,means for adjusting said arms angularly and a buffer member supportedbeneath said arms for vertical and angular adjustment and disposed inthepathway of the picker-stick.

5. A check for picker-sticks for looms including a frame supportedbeneath the lay of'the loom, a buffer member, and means supportingsaidmember including a pivotin a planeparallel to the plane of themovement of the picker-stick.

6. A check for picker-sticks for looms in.- cluding aframe supportedbeneath the lay of the loom, a buffer member, means supporting saidmember including a pivot in a of the picker-stick, and another pivot ina w. F. CLAYTON.
